US Patent 10941857 Self-shifting bicycle that shifts as a function of power output

A self-shifting bicycle that shifts intelligently as a function of power output. The bicycle uses a computer control system mounted to the handlebar, a power meter attached to the front gearwheel, and an actuator module for adjusting the transmission. The computer control system software changes output gear ratio in accordance with load encountered as the cyclist rides. This allows the rider to set a preferred power output and to maintain that preferred power output very closely.
